RedCatWaves...I completely agree with you. You had to let go of those friendships because they weren't respecting your wishes and hurting your feelings.
I would like to point out, though, that when thin women express unhappiness with their own bodies it doesn't necessarily mean that they think the same way about *your* body. When I was very thin, I hated my body. I had massive insecurities about my small breasts and my big behind.
My cousin, who has always been a big girl, believes that because I don't like my body then I must view hers in a negative way. This isn't true. While I would not want to be her size (if I can be honest), I do see her as beautiful. I don't judge her for being a size 16-18 because I believe that beauty comes in all shapes and sizes.
When thin women call themselves fat, they're often judging themselves harshly. Not you...although it feels that way. That is what they see in the mirror. I know it sounds insane but it's true. Sure, there are some people who do it just to be annoying but there are many women who are intensely unhappy with their bodies, regardless of size. When you hear a 110-lb. woman complaining about how "fat" she is, it is often because that's how she views herself...it has nothing to do with you.
That's just my perspective, though. You're right...life is too short to spend time with people who make you feel bad about yourself. I had to stop associating with people who were bringing me down so I understand where you're coming from.
Oh, I'm sure they are just trying to insult themselves, but when they are outright TOLD they are being insulting, and they continue to do it, I can only conclude they are then being willfully insulting to others.
And they weren't necessarily "making me feel bad about myself", because they weren't. They were just being insulting. Period.
